Bangabandhu Foundation President Moshiur Malek, who filed the case, said in his plea that Tarique described his father Zia-ur Rahman as the first president of Bangladesh at a programme in London on September 29.

After the case was filed, the judge ordered the Detective Branch to engage an officer not below the rank of an assistant commissioner on permission from the government to investigate the charge.

Rahman was arrested during the military-backed caretaker government in 2007 on charges of corruption. He had been implicated in a dozen of corruption cases then. After being released on parole, he went to the UK for treatment in September 2008 and has not returned since.
